Cannot add header information - headers already sent

Hi all, I’m stuck with this one: I have an checkout procedure: when people come to the overview page(step 2), they get: Warning: Cannot add header information - headers already sent by (output started at /usr/local/www/vhosts/aurelis.org/htdocs/header_aurelis.php:95) in /usr/local/www/vhosts/aurelis.org/htdocs/store/includes/functions/get_ca rtID.php on line 14 header_aurelis.php is where actual html output starts (template) i had a similar problem in my cart. I solved this by adding at the top of my script: $cookie = GetCartId(); This doesn’t do the trick now :-( For your convenience i put the code here: http://www.aurelis.org/store/checkout_form.txt and a handler file: http://www.aurelis.org/store/checkout_form_handler.txt Can anyone shed some light on this? Thanks! Fré
